3D tracking is the tracking of an object's position and orientation in a three-dimensional space.
3D tracking can be done in a number of ways, including electromagnetic tracking and camera-based tracking.
Methods of camera-based tracking include SLAM and VIO.
In general, tracking is either 3DOF tracking or 6DOF tracking.
History
3D tracking has been used for motion capture for 3D animated movies.
The 3DOF regime of cheap tracking was embraced by Oculus VR with the original Oculus Rift.
Methods
- Electromagnetic tracking. Electromagnetic tracking requires an external source. It also does not work reliably in the presence of metallic objects, like a metal water bottle or laptop computer. Magnetic tracking is typically wired, but it does not have to be.
- UWB tracking
- Camera-based tracking
- Inertial tracking
